Great name – throw it in the pit – very evocative! This is a small black plastic box, lined with foam, ventilated at both ends, fitted with a pin on the back. The idea is I pin this to my waistcoat, shirt, jacket or whatever, and use it as a fly patch. A simple, practical idea! More and more flies are barbless or debarbed and fall out of my various fly patches far too easily and too often, I lose flies I want, I find flies in places I don't want them, e.g. the car boot, and the dog.

Nicely made, good quality plastic, the hinge is pinned so it should last. Inside Tiemco have lined one side with foam bars – think dries – and the other with flat foam, plus I have four stick-on foam bars if I need them.
Simple product – good idea!
